E60 M5 DME......
Discussion
The battery in my M5 went flat last week. I arranged to pick up the replacement battery from BMW and they to dive it to them to code it. Long story short, the car was as flat as a pancake so i called the RAC out. He tried to jump start it with no joy. After about ten minutes he realised that the negative cable for his jump start was faulty which was why my car was not getting any charge. Anyway, it then got low loaded to BMW.
BMW spent an hour fitting the battery and recoding it and then tried to start it. All it did was crank and did not fire. After another hour they came and told me that the DME module is faulty and needs to be replaced at £1600!!
So, my question is. Could the RAC have caused this with the faulty jump start lead and having a positive charge running into my car with no 'earth' so to speak for ten minutes? Or, are BMW playing around with my cash and telling me what they 'think' it might be and this is the easiest option to start with?
My thought is that if the battery died the car probably needs to relearn the 'key code' so it knows it's the correct key that is trying to start it (it's the comfort key-not the old fashioned one). Does anyone have any thoughts or experiences when this has happened to them? I can't imagine a flat battery then causes a £1600 bill by coincidence!!
Thanks

sorry to hear your problem
is there a possibility of contacting tuners like Evolve to have a look at it and perhaps get it fixed at more affordable price? at the same time you'll be squeezing out a couple dozens of extra horses..
or perhaps you could try getting second hand DME module from salvage cars
the problem is that the BMW's diagnostic can be wrong and obviously the last thing we want is forking out your money to replace every single part that is in suspicion of causing this problem starting with DME module.
I remember a member on M6board.com having very similar situation as yours which turned out to be loose starter motor battery cable. It was rusted and loosened. BMW diagnosed it as faulty starter motor. His car was under warranty so he didn't have to pay for a new starter+12hour labour.

Check the battery cable and other visible items in your engine bay.
hope this helps,
good luck!

Thanks. It cranks, it just does not fire so i'm assuming the starter motor is ok.
They tell me today they have run the other tests and it's not anything other than the ECU according to them. I've already told them i won't be happy if they get me to replace this and then it's not that.
Will give Evolve a ring and see what they say.
This has all stemmed from the RAC jump starting it-a warning to all of you, never jump start an M5 as it fry's the electronics!

Did they try and jump it by connecting directly to the battery in the boot? You can jump start M5s using terminals in the engine compartment... it's documented in the manual so shouldn't fry the electronics even with faulty leads!

Apparently BMW say they see this a lot, someone jump starts a car and cuases an electrical surge which does this kind of damage. It's pot luck who it happens to apparently but they tell me to have the side lights on if you need to do it in the future as the surge will head to these and blow these rather than expensive computers.
As a side note, it looks like i've got no choice but to go to BMW buy the new DME module and have it coded. I spoke to evolve automotive and they said the same. The RAC will be getting a nice letter from me as well as i'm sure it was their duff jump leads that cuased the positive charge to go into the car and cause this!!

Quick update on this. The garage still have the car, it now looks like water leaked into the DME as the seal around the DME cover had perished. Worth checking how yours is looking as i'm sure with age more and more of these issues will occur and a seal is cheaper than the bill i'm about to pick up on monday.
They also said it's worth clearing the drain holes under the microfilters (it's a ten minutes job apparently) as leaves and general debris collect there and prevent water flowing away. Once it gets to a certain height it's bye bye DME and hello to a big bill!
